No, it was "interest only" loans, sub-prime loans, and people just generally biting off more than they can chew with the expectations that property values will always increase that actually got us into this trouble. Interest only loans are particularly bad - sort of the mortgage version of making the minimum payment on a credit card and never chipping away at the principal.
After my 7 year ARM is up, the max the rate can go up is like 4 points - and that is only if Prime is soaring (i.e. total market recovery, inflation and the next internet/housing bubble on the rise.) The ironic thing is that even if the worse case transpires for me - we decide to stay for more than 7 years, the economy is booming and rates soar, and we can't refinance due to shitty credit - our rate can only go to about what it was before we refinanced. And after paying it down for 7 years, the math works out so that our new, worse-case scenario payment would actually be less than what we were paying before the refinance. These worse-case payment amounts were all spelled out in my Truth-in-lending disclosure, plain as day.
Also, the 5/5 ARM that Penfed has is pretty awesome. They cover most of the closing costs, and it can only adjust by 2 points in 5 years, and then another 2 points 5 years after that. Again, worse case scenario, in 10 years you wind up paying the rates that you paid in 2008 or so, which was when I had my original loan.
So if you are saying that I will regret saving $600/month for 7 years ($50K total, for those bad at math), and then possibly, worse-case going back to my old monthly payments, you are one of those who doesn't understand money or high-school math, and you are a prime candidate for Ramsey's junk. Besides, I know that I am not going to be here for 30 years, so if I bought a 30-year loan, I am throwing away the closing costs the moment I sell or refinance.
Mapplby is dead right. I have said time and again, Ramsey's shit is for those who truly don't understand money or numbers. His prescriptions and strategies will lose you wealth over the years - and lots of it. Making people think that investments and capitalism (oh, I am sorry, if you are on the receiving end of someone else's capital investment, it is known by its evil name - debt) is always bad, is just ludicrous. Telling people not to take out the max amount of money at 2.5% with a 30 year term so you can invest it and gain 5-10% is complete and total financial idiocracy, by definition and by the numbers. All because of his scare tactics that "all debt is bad." Absolutely crazy. I wish my bank would let me load up on another $200K of that evil debt at today's mortgage rates with a 30-year lock in. I could make a killing with that money - especially 10-15 years down the road when rates go up. Borrowing at 3% on a mortgage today is basically like free money, due to the effects of inflation.
But at the end of the day, why the fuck would someone lock themselves into a financial product for 30 years, knowing full well that they won't be in that house for 30 years, and thus enjoying the benefits of the 30 year lock in???? By definition, if you know you are only going to be using a financial product for, say, no more than 10 years, why would you buy a product, appropriately labelled, with "30 year" in the title? The higher rates you are paying by not going with a 7 or 10 year loan is just Dave Ramsey-type money - pissed away as a penalty for those who don't understand math.
